Corrugated comb frequency selective surfaces for control of wireless propagation in buildings

This paper presents simulation and measurement results of a corrugated comb reflection frequency selective surface (CR-FSS). Surface parameters are altered to investigate the effect of sloping the comb elements to produce a corrugated structure. It is proposed that the strength of such elements can therefore be increased, however the effect on the reduction in specular scatter is unknown. CST simulations and measurement results on foam and foil prototypes provide evidence that increasing the slope angle can alter scattering performance. Furthermore, issues with manufacture and the application of such surfaces are discussed.
